After Effects presets not animating in Bridge CS6

In After Effects CS6, when I choose to "Browse Presets" from the Effects & Presets tab, Bridge CS6 opens up and I can navigate through all the preset folders. When I get to the specific presets I want to preview, though, the animation does not play - it just sits on one frame. If I open up this same folder with Bridge CS5.5, however, these presets will actually play as an animation so I can see exactly what they do. Why isn't Bridge CS6 doing this too?
